Tuesday Health Report: New AstraZeneca Drug May Be First to Reduce COPD Symptoms, FDA Approval Sought

AstraZeneca said the first-in-class antibody reduced moderate and severe flare-ups by up to 34% in late-stage trials.

  • Results presented Tuesday at the European Respiratory Society Congress show AstraZeneca's drug tozorakimab demonstrated promise in reducing COPD symptoms during late-stage clinical trials.
  • Nearly 16 million U.S. adults suffer from COPD, a leading cause of death often linked to tobacco, though one in four patients have never smoked, the CDC reports.
  • Patients receiving 300 milligrams of tozorakimab every four weeks saw symptom reductions ranging from 29% to 34%, according to data from two separate AstraZeneca-sponsored clinical trials.
  • The Food and Drug Administration accepted tozorakimab for priority review as an add-on maintenance treatment for adults, marking the first biologic drug for COPD management.
  • Ongoing investigations are evaluating tozorakimab's potential application for asthma and lower respiratory tract disease, expanding on its development as a monoclonal antibody targeting inflammation.
